Introduction to LT1962EMS8#PBF Voltage Regulators

The Linear Technology LT1962EMS is a high-performance fixed-output voltage regulator, built for applications where components need high efficiency, fast transient response, high power density and minimal heat output. As part of the PMIC - Voltage Regulators - Linear family, the LT1962EMS is a voltage regulating system-on-chip (SoC) that can provide high-performance linear power regulation in a wide variety of applications.

Application Field of LT1962EMS8#PBF Voltage Regulators

The LT1962EMS8#PBF voltage regulator is designed for applications that demand improved power efficiency and high-power density. This regulator is ideal for portable and mobile applications such as personal digital assistants (PDAs), notebook computers, and many other power-sensitive applications. It is also suitable for battery-powered applications, where high efficiency and an extremely low quiescent current are paramount. Additionally, the LT1962EMS8#PBF voltage regulator is an ideal choice for automotive systems, where rugged operation and higher output currents are required.

Functional Layout of LT1962EMS

The LT1962EMS voltage regulator features an integrated Power amplifier and Dynamic Output Impedance Adjustment (DOIA) circuit. The SO IC integrates a sense terminal and dynamic output impedance adjustment into a single chip, providing a high-accuracy, high-power regulator. The SO IC also provides protection and guarantees a stable output voltage during load transients.Additional features include thermal shutdown, overcurrent protection and brownout undervoltage protection. In addition, the LT1962EMS8#PBF voltage regulator provides both linear and discontinuous conduction mode (DCM) operation, offering lower operating temperature and higher efficiency.

Working Principle of LT1962EMS Voltage Regulator

The LT1962EMS voltage regulator works by adjusting the output voltage based on a sensed voltage in the feedback loop. When the load is between 20% and 100%, the current is regulated across the output via the sense terminal. When the load falls below 20%, the current is regulated via the DOIA circuit, which eliminates the need for a soft-start resistor. The integrated power amplifier provides fast transient response, allowing the output voltage to track the input voltage, even at low loads.

Conclusion

Overall, the LT1962EMS8#PBF voltage regulator offers high efficiency, low quiescent current and fast transient response in a small package, making it an ideal choice for a wide range of applications.The voltage regulator\'s integrated features provide good protection in adverse conditions, allowing it to operate reliably in environments where conventional linear regulators struggle. Additionally, its ability to switch between linear and discontinuous conduction modes increases efficiency in low-current applications. The LT1962EMS8#PBF voltage regulator is a cost-effective solution for applications with stringent power requirements.
